Is 8GB of Vram enough for the 3070

You realise you can get FE cards for cheaper than 750 that wipe that 6700XT right?
and while most of the 3080tis prices are an absolute rip off i wouldnt really compare one with a 6700XT merely based on their VRAM lol

FE prices kept artificially low, as Nvidia also need to scam their AIB partners...and then by extersion, the customer again...

:cry:

If you know you know...

Timespy benchmarks..... oh lordy :o

In most game benchmarks, they are comparable.


Only because the benchmarks you've seen are stock. The 2080ti is a monster overclocker that destroys the weak sauce 3070. The 2080ti can run up to 50% faster in games compared to its stock performance by overclocking, the 3070 gets what, 5 or 10% of that?

When Nvidia announced the 3080 and showed it running Doom Eternal, 2080ti owners were already laughing because anyone who overclocked their 2080ti was getting the same performance as the 3080 - that was the reason why I didn't buy the 3080, it's performance was not really better than my 2080ti

"exotic cooling".... :cry: And how many people do that?

I know the 2080ti is a good clocker, even with stock cooling and perhaps the extreme overclock models do have it win more than a "stock" 3070 in non ray tracing titles but I would say it is far and few between, especially once nvidia stop optimising for turing, if they haven't already done so....

As for a OC 2080ti "matching" a 3080, not sure about that now from a quick look at various videos:





And that's not even showing most of the new RT titles where ampere RT perf. is over twice the perf. of turing.

Even in doom eternal, 3080 still looks to have the lead....


CPU avg : 3.70 ms (270 FPS) vs 2.42 ms (413 FPS)
GPU avg : 7.75 ms (129 FPS) vs 9.04 ms (110 FPS)
total avg : 8.23 ms (121.5 FPS) vs 9.62 ms (104 FPS)

That's roughly a +17% increase from a heavily overclocked 2080Ti. The stock 2080Ti was shown at 11.89 ms which is 84 FPS avg, that would mean a 44,6% increase from a stock 2080Ti.

Unless are we referring to some 2080ti on liquid nitrogen?

while valid point I dont think most people bother running RT even if they can

Can't speak for everyone but I think it is safe to say most ampere owners do keep ray tracing turned on especially when looking at threads such as cyberpunk, control, metro, guardians of the galaxy etc. where you see people keeping it on. As a 3080 owner, I certainly do anyway, will sacrifice other settings before turning off rt because it makes more of a difference than using "ultra" settings.

You're missing out (IMO).

Looks great in Control and Cyberpunk2077, the main RT titles I've tried so far.
Agree it is worth turning on in those games. Looks nice and you get to enjoy it. I even like it in Minecraft when I play with my lad :)

Definitely recommend the following to feast your eyes on RT goodness:

- the ascent
- cyberpunk
- metro enhanced
- bright memory infinite
- control
- watch dogs legion

Good YT channel that shows the difference of very well:

With a 3080, you'll have no issues with perf., use dlss quality for 1440p and balance for 4k.

Thanks, I'll take a look.
I do own Cyberpunk from when it was released but decided to stop playing until the issues were ironed out. Since then I got a bit involved with other games and forgot about it.

Uhm.. yeah it is enough...

Also.. 2080 Ti territory (Overclocked 2080 Ti's) 2040mhz ish, so that's all the lower end models that peak around 2050mhz.

And my 3070 is a lower end inno3d iChill x4.

RTX 3070 2055mhz (2025-2040 average) 7951mhz memory.
Ryzen 5 5600x stock with CL16 3733mhz DDR4
511.65 driver.
Windows 11 Pro 64

So go ahead and buy the 8 GB card, don't be mad at me for pointing out the facts. And your comparison to 64x AA is disingenuous because while that kind of a workload would be near impossible to run by any hardware, present or future, all these settings require is a bit more memory. THAT'S IT! You don't even need a more 'powerful' (processing) card.
What facts?

Ooh another memory heavy game

25gb memory used at 4k with RTX GI.


with RTX GI off memory usage drops by 10gb!
9.5GB Vram used which means any 8GB Vram buffer will be completely fine since the usage you are seeing is what the game allocates, not what is needed which is a lower amount than this, sometimes substantially less.
